Garmin GMI/GNX Wired Sail Pack 52

The Garmin GMI 20 and GNX 20 Wired Sail Pack 52 combines a color instrument display with a monochrome sailing display and DST810 smart transducer. It is designed for boats that need wind, depth, speed, temperature, and other NMEA 2000 data visible across more than one instrument. The displays are compact enough for a cockpit cluster, while the included sensor handles depth, speed, and water temperature.

The GMI 20 offers a 4-inch color LCD at 320 x 240 resolution and 700 nits, while the GNX 20 adds a low-power monochrome data display. Both displays connect through NMEA 2000, and the DST810 uses Bluetooth for calibration. The pack is rated IPX7 and runs from 9-16V DC. It is an instrument bundle, not a chartplotter, and the supplied specifications do not list a gWind masthead sensor in this version.

Who Is This For?

This NMEA 2000 sailing instrument kit suits cruising boats and sailboats that need dedicated cockpit data displays and a DST810 sensor. It is not ideal for buyers wanting charts, radar, or a complete wind package, because the supplied specification does not list a masthead wind transducer.

Warranty & Support

Garmin provides a 2-year manufacturer warranty. The supplied specifications do not state warranty exclusions or service procedures.

The GMI/GNX Sail Pack is a practical instrument kit when the boat needs two display styles and a DST810 sensor but does not need the larger gWind package. Its trade-off is wind coverage: the supplied specification does not include a masthead wind transducer. Choose it for depth, speed, temperature, and NMEA 2000 data, and add the appropriate wind hardware only if the sailing system requires it.
